I am not sure whether this is the best newsgroup to address this
question. But certainly, it is read by a lot of people. The question
that I want to address is whether the organisms have any advantage
having uracil in RNA. The question was asked by a professor in an
undergraduate microbiology class as a thought question. The student
came and asked me. I had never thought about it before and could not
come up with any explanations. I am sure that there is a good reason
for having uracil in RNA. Does anyone have any thoughts about it.
Please reply ASAP.
Thanks in advance.
